FIELD OF INVENTION

[0002] The present invention relates to cooking appliances and, more particularly, to a food serving set for use with a roasting oven or other similar deep well cooker including both a collapsible supporting rack for food containers, which can be folded or disassembled for storage and packaging within the roasting oven and, in the alternative, a non-collapsible supporting rack for such food containers.

BACKGROUND OF THE INVENTION

[0003] Electric cooking pots for preparing and serving hot foods are well known in the prior art. Such cooking pots typically include a deep well member and a heating element arranged in functional relation thereto for supplying heat. Such cooking pots may be provided with compartmented trays, which are disposed within the interior space of the cooker for reheating and maintaining food in a ready-to-eat condition.

[0004] However, such compartmented trays are not convenient for the storage of leftover food items due to size constraints within a typical refrigerator. Further, such serving trays typically are not easily handled when hot, are not stackable (i e one within another) to save space, and are not conveniently packaged at the time of manufacture due to the lack of available space within the interior cavity of the roasting oven. As a result the food trays must be packaged and shipped separately, which increases overall manufacturing costs.

[0005] Thus, the present invention has been developed to resolve this problem and other shortcomings of the prior art

Each latch assembly 120 is comprised of a tongue bracket 122 which is installed in sliding engagement with a mating hasp 124 such that the half sections 115 a′, 115 b′ are detachably secured in position.

[0055] In the embodiment seen in FIG. 3D, the supporting rack 115′ is a stamped metal construction and tongue brackets 122 and hasps 124 are secured to the half sections 115 a′, 115 b′ by weldment or other suitable fasteners such as rivets.

[0056] It will be appreciated by those skilled in the art that various other types of attaching hardware and quick connect/disconnect fasteners may be utilized for detachably securing the half sections 115 a′, 115 b′ of the supporting rack 115′ and such attaching hardware is understood to be within the scope of the present invention

[0057] With reference to FIGS. 4A-4C there is shown another embodiment of the food serving set, indicated generally at 100′, that is designed for use with the roasting oven 10. In this embodiment a non-collapsible supporting rack 215 is configured to reside in the top opening of the roasting oven 10 engaging the flange member 45 a of the cooking liner 45 as shown in FIG. 4C. In practical use the liner 45 is filled with water to a sufficient level as at 50 to contact the food containers 105, 110 when disposed in the supporting rack 215 in order to heat the food items contained therein.

[0058] In another embodiment the half sections 115 a″, 115 b″ of a supporting rack 15″ are permanently joined by hinge assemblies, indicated generally at 130, as shown in FIG. 5. Thus, the supporting rack 115″ is foldable 180 degrees onto itself to the position shown for convenient storage within the interior space of the roasting oven 10. Thereafter, the supporting rack 115″ is unfolded to a flattened condition for use with the present roasting oven 10 as described hereinabove.

[0059] Of course, the present serving set including the supporting rack can also be adapted for use with roasting ovens or other deep well cookers having different geometric configurations. Referring to FIGS. 6A and 6B there is shown therein a modified supporting rack, indicated generally at 115′″, which is oval in configuration having modified openings 106″ and 111″ formed therein. The food containers (not shown) for this embodiment are configured for mating engagement with their corresponding openings 106″, 111″. In this embodiment semi-oval half sections 115 a′″, 115 b′″ are detachably secured by a transverse bracket member 125 whereon a pair of modified tongue brackets 122″ are mounted for sliding engagement with mating hasps 124″ as shown in FIG. 6B.

[0060] In an alternative construction shown in FIG. 6C, a non-collapsible supporting rack 215″ is provided, which is also oval in configuration having the same modified openings 106″ and 111″ formed therein. The food containers (not shown) for this embodiment are also configured for mating engagement with their corresponding openings 106″, 111″. The oval supporting rack 215″ includes pivoting lift-out handle assemblies 225 for conveniently lifting the present serving set from the roasting oven during use.

[0061] In FIG. 7 there is shown yet another embodiment of a collapsible supporting rack, indicated generally at 115″″, which is generally rectangular in configuration. The supporting rack 115″″ is divided into three separate sections, namely, two D-shaped end sections 115 a′″ and a center section 115 b″″ each having a generally rectangular opening 132′″ with corner radii for receiving a mating food container (not shown).

[0062] As more clearly shown in FIGS. 8A and 8B, each of the D-shaped end sections 115 a″″ is a unitary construction conforming to the inner edge of the flange 45 a of the cooking liner 45 (FIG. 3C). It can be seen that each end section 115 a″″ includes a pair of receptacles, indicated generally at 135, which are recessed into the upper surface of each end section 115 a″″. In the embodiment shown receptacles 135 are cut and stamped into the sheet metal end sections 115 a″″ in a metal fabrication process such that rectangular sections 135 a are displaced approximately {fraction (1/8)} to {fraction (1/4)} inch from the upper surface, but remain integrally attached thereto. The slotted openings 135 b are so formed for receiving mating tabs 136 formed on the center section 115 b″″ shown in FIGS. 9A and 9B.

[0063] Referring to FIG. 9C there is shown another embodiment of a non-collapsible supporting rack 215′″, which is also generally rectangular in configuration. This embodiment of the supporting rack 215′″ includes three generally rectangular openings 132′″ with corner radii for receiving mating food containers 104 having a corresponding contour as shown in FIG. 9D. In this embodiment the supporting rack 215′″ includes pivoting lift-out handles 225 at opposite ends thereof for conveniently lifting the present serving set from the roasting oven during use. In addition, each of the individual food containers 104 is provided with pivoting lift-out handles 225′ for lifting the food containers from the supporting rack 215′″ when in use.

[0064] In yet another alternative embodiment of the present serving set 100″ as shown in FIG. 10A, a supporting rack as described hereinabove is unnecessary due to the modified configuration of the food containers. In this embodiment three generally rectangular food containers 105′, 105″ including peripheral flanges 105 b′, 105 c″ respectively are configured to fit the inner edge 45 b of the flange 45 a of the cooking liner 45 as more clearly shown in FIG. 10B. It can be seen that the peripheral flanges 105 b′ of the outer pair of containers 105′ are generally D-shaped in configuration being interchangeable and fitted to the opposite ends of the cooking liner 45.

[0065] Still referring to FIG. 10B, the center food container 105′ includes a rectangular, peripheral flange 105 c″, which is configured to fit the central portion of the inner edge 45 b of the cooking liner 45 as shown. It will be understood that in FIGS. 10A-10B the lateral edges 105 d″ of the flange 105 c″ of the center container 105″ are configured to form a butt joint with the adjoining lateral edges of the outer pair of food containers 105′.

[0066] In an alternative construction shown in FIG. 10C, the lateral edges 105 d′″ of the flange 105 c″of the center container 105′″ are bent at a predetermined offset angle and are positioned in overlapping relation with the corresponding lateral edges of the outer pair of food containers 105′. In a preferred construction the lateral edges 105 d′″ are bent at a 90° offset angle. In this manner the center food container 105′″ shown in FIG. 10C engages and overlaps the outer containers 105′ maintaining the containers in position.

[0067] The food containers 105′, 105″, 105′″ are fabricated with inwardly tapered sidewalls to permit the food containers to nest together in stacked relation as shown in FIG. 10D for convenient packaging and storage of the food containers.

[0068] In another embodiment of the food serving set illustrated in FIG. 10E, the individual food containers 105′, 105″, 105′″ may be provided with pivoting lift-out handles 225′ for lifting the food containers from the cooking liner 45 during use.

[0069] Similarly, a supporting rack is unnecessary in the embodiment of the food serving set 100′″ illustrated in FIGS. 11A and 11B. In this oval configuration of the cooking liner 45″, the two food containers 105″″ including peripheral flanges 105 a′″ are configured to fit the inner edge 45 b″ of the flange 45 a″ of the cooking liner 45″. It can be seen that the peripheral flanges 105 a′″ of the pair of containers 105″″ are semi-oval in configuration being fitted to the opposite ends of the cooking liner 45″.

[0070] Referring now to FIG. 12A there is shown yet another embodiment of the serving set, indicated generally at 100′″″, wherein a supporting rack is not required. In this configuration of the serving set, a single large food container 105′″″ including peripheral flange 105 a′″″ and two smaller food containers 110″″ including peripheral flanges 10 a″″ are configured to fit the inner peripheral edge of the cooking liner 45. It can be seen that the inner lateral edges 110 b″″ of the peripheral flanges 110 a″″ of food containers 110″″ are bent at a 90° offset angle and are positioned in overlapping relation with the corresponding lateral edge of the larger food container 105′″″. In this manner the smaller food containers 110″″ engage and overlap the larger container 105′″″maintaining it in position. A protuberance 155 is formed adjacent the midpoint of the inner lateral edge of flange 105 a′″″, which functions to maintain the smaller food containers 110″″ in position.

[0071] Thus, it can be seen that the present invention provides a versatile food serving set for use in combination with a roasting oven or other deep well cooker, which can be utilized for maintaining food items in a ready-to-eat condition. The food serving set features individual food containers having sealable lid members, which can be transferred directly from the refrigerator to the cooker. The food serving set includes a supporting rack, which positions the food containers within the cooker during use, and which is collapsible for efficient storage and/or packaging within the interior space of the cooker. In various alternative embodiments the supporting rack is non-collapsible or is not required as the food containers are provided with integral flanges, which conform to the inner peripheral edge of the cooking liner and support the food containers in position.

[0072] Although not specifically illustrated in the drawings, it should be understood that additional equipment and structural components will be provided as necessary, and that all of the components described above are arranged and supported in an appropriate fashion to form a complete and operative food serving set incorporating features of the present invention.

[0073] Moreover, although illustrative embodiments of the invention have been described, a latitude of modification, change, and substitution is intended in the foregoing disclosure, and in certain instances, some features of the invention will be employed without a corresponding use of other features.
